Free song if you sign up to my newsletter... Does it work? Week 7

So... continuing on with my Songwriters Association of Canada Blogging Challenge, I have a general question for all you folks.

I give away a free mp3 of one of my songs in exchange for fans signing up to my email newsletter. What do you think? Is this a good value for you?

Part of me thinks if you want to find up for my updates, you'll sign up anyway. But I also want to maybe tip over the folks on the fence. Is this a good deal? Something free in exchange for an email?

Let's back up a bit. I started my newsletter to give fans an update of what's going on with me. Tour dates, new songs etc. I strive to be interesting and entertaining... just like my live shows... and hopefully it's working.

Here's your chance to tell me what you like and don't like about my newsletter. Lay it on me: Seriously, I want to know so I can get better. You won't hurt my ego... there ain't much left of it anyhow!
